Work / Energy / Momentum (6) Flashcards
(8 cards)
1
Q
Work
A
- W = Fd
- W = Fdcosx
2
Q
Kinetic energy (FS)
A
- Ke = 1/2mv^2
- Ke = P^2/2m
3
Q
Gravitational potential energy (FS)
A
- Pe = mgh
4
Q
Conservation of mechanical energy (FS)
A
- E(total) = Pe + Ke = constant
5
Q
Work energy principle
A
- deltaPe + deltaKe = W(nc)
- E(final) - E(initial) = W(nc)
6
Q
Power
A
- P = W/t
- P = Fv
7
Q
Momentum (FS)
A
- p = mv
8
Q
Changing momentum/Impulse (FS)
A
- sigmaFt = deltap
I = F*delta
